PV=nRT

• 14.19 atm

• 16.53 atm

What will happen to the volume of a gas if the pressure increases, with constant temperature ?

• Increase

• Decrease

• Nothing

• Explosion!

When the temperature of matter increases the particles...

• speed up and move closer

• speed up and move farther apart

• slow down and move closer together

• slow down and move farther apart
